The TSC and GTRI Sea Clutter Models 1,2 are empirical models with a theoretical dependency for wind direction. Observations collected during at-sea testing have forced a reappraisal of the wind aspect factor, as predicted and observed minima in the crosswind direction were not treated by the model.We modified the wind aspect factor to reflect theory and observation, and now have excellent agreement among model, theory, and observation.

Abslracl -An L-band total power receiver for use in a synthetic thinned array radiometer (STAR) is described. The total power architecture of a radiometer receiver requires special considerations to control gain fluctuations due to small temperature drifts. The STAR application requires consistent passband and stable phase between receiven. The design presented incorporates direct detection to eliminate distributed local oscillators for phase stability, distributed ceramic interference reject filters for passband consistency and temperature compensating atteuuatnrs for gain stability. The receiver is packaged in a unique "winged-hex'' shape to enable close packaging with the STAR antennas and to facilitate thermal management. The resulting low cost, compact receiver is made from COTS components.

In digital system design, the Linear Feedback Shift Register (LFSR) is the queen of logic functions, and the design engineers can use LFSR in both hardware (HW) or software (SW) implementation. In this paper, LFSR will be discussed in its HW implementation via Hardware description language. In addition, the application of LFSR in of pseudorandom number generator (PRNG), direct sequence spread spectrum (DSSS), cyclic redundancy check (CRC) is also given.
